BIO-UV Completes First Containerized Ballast Water Treatment Deployment

BIO-UV Group has completed the first commercial deployment of its containerized BIO-SEA ballast water treatment system (BWTS) at Port-la-Nouvelle in southern France, supporting the installation of the pioneering EFGL floating offshore wind project in the Mediterranean.

BIO-UV’s containerized system was used to treat the water deballasted from three floating wind turbine platforms – each comprising three floaters arranged in a triangular structure – before their deployment offshore.

The rental agreement, signed with Euroports in May 2025, enabled Euroports to provide compliant deballasting services including the water treatment to EFGL during the assembly and installation phase. The first platform arrived from Fos-sur-Mer near Marseille in early July, followed by the second in mid-July and the final unit in August. Over the course of approximately two months, BIO-UV treated the ballast water of all three platforms in full compliance with IMO D-2 standards and local environmental regulations, before safe
